came up on a constructor. According to the xamarin forums this is a VS bug, which I tried to fix with
％ProgramFiles（x86）％\ Microsoft Visual Studio \ Installer \ resources \ app \ layout \ InstallCleanup.exe -i
While this did not solve my constructor problem, I found another way to achieve my goal and I worked out a solution without interfaces. Netherless, after restarting my PC, it seems like Visual Studio wont open sln files anymore. When I doubleclick them, a window which tells me to select an application to open the file appears
I also cant use the VS installer anymore. There is no repair or uninstall option and if I click install it fails because the Visual Studio directory isnt empty.
